Addedclaude auto-mode reset to restore the default auto-mode configuration, with a confirmation prompt (pass `--yes` to skip)
Added a session-wide limit on WebSearch tool calls (default 200, tunable via `CLAUDE_CODE_MAX_WEB_SEARCHES_PER_SESSION`) to stop runaway search loops
Added a per-session cap on subagent spawns (default 200, override with `CLAUDE_CODE_MAX_SUBAGENTS_PER_SESSION`) to stop runaway delegation loops; `/clear` resets the budget
~changed 12
/fork now copies your conversation into a new background session (its own row in `claude agents`) while you keep working; the in-session subagent it used to launch is now `/subtask`
MCP tool calls running longer than 2 minutes now move to the background automatically so the session stays usable; configure the threshold or disable with `CLAUDE_CODE_MCP_AUTO_BACKGROUND_MS`
Typing /resume in the agent view now opens a picker of past sessions — including sessions deleted from the list — and resumes your pick as a background session
Changed/fork to name the copy after your prompt when the session has no title, so the row is recognizable in the agent view
Changed bare /btw to reopen the side-question panel on your most recent exchange so you can browse earlier answers
Changed the ← footer hint to pulse `N done` for a moment when a background agent finishes while nothing needs your input
Changed Enterprise forceLoginMethod to be enforced for VS Code extension, SDK, `setup-token`, and `install-github-app` logins, not just the terminal
Changed session transcripts to record the reasoning effort level on each assistant message
Changed headless/SDK sessions to apply a `set_model` control request mid-turn; the next model round-trip uses the new model instead of waiting for the next turn
Changed agent view / claude agents --json: sessions waiting on a sandbox, MCP-input, or managed-settings prompt now show as "Needs input" instead of "Working"
Updated the auth status panel title from "Cloud authentication" to "Authentication"
Corrected an earlier release note (2.1.200): tmux through the 3.6 series lacks synchronized output; newer tmux with support is detected automatically
−removed 1
Deprecated the Task tool's mode parameter (now ignored); subagents inherit the parent session's permission mode by default
↑improved 4
Improved web search and web fetch reliability by retrying 529 errors and rate-limited requests with bounded backoff
Improvedprompt caching: the mid-conversation system block now works behind LLM gateways and custom base URLs (Bedrock, Vertex, 1P)
Improvedbackground agent attach: cold-attaching now instantly shows the formatted transcript while the session boots, instead of a blank wait
Reduced token usage in inter-agent messaging: `SendMessage` bodies are no longer duplicated into replayed history and tool results
✓fixed 28
Fixed plan mode auto-running file-modifying Bash commands (e.g. `touch`, `rm`) without a permission prompt or SDK `canUseTool` callback
Fixed worktree creation following a repository-committed symlink at `.claude/worktrees`, which could create files outside the repository
Fixed a continue:false hook's halt being dropped when the tool fails or completes mid-stream, and hook infrastructure errors being misreported as user rejections
Fixed SIGTERM during a running Bash tool orphaning the command's process tree in print/SDK mode; the CLI now aborts the turn, kills the tree, and exits 143
Fixed/background and `claude --bg` failing with "EUNKNOWN: unknown error, uv_spawn" on Windows when Group Policy blocks PowerShell 5.1; the daemon now prefers PowerShell 7
Fixed shell mode (!) not executing commands containing file paths while the path autocomplete popup was open
Fixed auto-mode denial notifications rendering broken characters when a long denial reason was truncated mid-emoji
Fixed Ctrl+J not inserting a newline in the agent view dispatch input on terminals with extended key reporting, and surfaced the newline shortcut in the `?` help overlay
Fixed/ultrareview rejecting PR references like `#123`, `PR 123`, and pasted PR URLs; error hints now name the command you actually typed
Fixed/ultrareview <branch> not fetching the branch from origin when it exists remotely; it now suggests the closest branch name on typos
Fixed/ultrareview skipping the billing confirmation in a new conversation after `/clear`
Fixed/ultrareview's "not a git repository" error on Claude Desktop now suggesting the project's repository folder instead of terminal commands
Fixed hosted (host-managed) sessions failing at startup when repository settings configured mTLS certs, extra CA bundles, or OAuth scopes; these transport settings are now ignored with a warning
Fixed a spurious "File has not been read yet" error when editing a file that had been read with offset/limit before resuming a session
FixedExitWorktree failing with "no active EnterWorktree session" after resuming a session with `--continue`/`--resume` in print/SDK mode
Fixed the workflow agent grid staying empty for Remote Control clients that join a session mid-run
Fixed streaming-mode control requests being marked complete before their handler finished, which could lose the request on session restart
Fixed background sessions created with `/fork` losing their live-parent protection after a state write failure
Fixed reopening a stopped background session from the agent view failing silently — it now resumes the session, or shows why it can't and lets you force a restart
Fixedagent teams: a stopping teammate could send the leader duplicate idle notifications when team initialization re-ran within a session
Fixed the plan-approval dialog footer splitting "ctrl+g to edit in <editor>" apart when the file path is long
Fixed the welcome banner keeping its old panel widths after a combined width+height terminal resize in fullscreen mode
Fixed diff previews losing their line numbers and +/- markers in narrow layouts
Fixed @-mentions attaching nothing after a partial file read, plugin uninstall targeting the wrong marketplace, and false "Command timed out" on exit code 143
FixedOpenTelemetry HTTP exports being rejected with 411/400 by Azure Monitor and other endpoints that don't accept chunked transfer encoding
Fixed OTLP event log records missing `trace_id`/`span_id` when `TRACEPARENT` is set in SDK/headless mode
Fixed conversations with many images incorrectly failing with "Request too large" errors, and improved the error message to explain the actual cause
Fixed web search and web fetch returning "API Error" text as search results or page content when the API was overloaded
